Somewhere in your code, the variable "items" is being defined as a function.
Skim through your code and make sure that the variable is unique, and nothing else is overwriting the variable.
Here's a tip: If lua ever says you're trying to index something invalid, you're probably trying to path a variable / object that is nil, or doesn't have a path.
For example, you can't do this:
```lua function a() end
print(a.waffle) ``` because "a" is a function, and it has no path. Doing this will throw the error that you're getting right now.
However, you can do this:
```lua local Table = { A = { B = { C = 'waffle' } } }
print(Table.A.B.C) ``` because the Table can be indexed and pathed like how you would when you're browsing through workspace, or anywhere else.
You also cannot do this:
lua
local NilValue = nil;
print(NilValue.Descendant)
as it will throw an "attempt to index local NilValue ( a nil value)" error. Good luck!
